A handyman known to the Smarts as "Emmanuel" has been identified as Brian David Mitchell, police said Tuesday. The family said he worked for them in November 2001.

Police have been looking for the man since October, when Elizabeth's younger sister, the sole witness in the June 5 disappearance, told her parents that she thought Emmanuel could have been the kidnapper.

They identified Emmanuel as Mitchell when the man's sister contacted them after the Smarts showed a sketch of him at a Feb. 3 news conference.

Mitchell was identified Saturday on the television program "America's Most Wanted." Police say he is a "person of interest" but not the focus of the investigation.

Investigators had focused on handyman Richard Ricci as a potential suspect but never charged him. He died in August.
